The Free Radical Club of Grenoble gathers about one hundred researchers in the Grenoble area and organizes not only a local scientific animation but also international courses on techniques on Free Radicals and Winter Conferences on specialized topics. The Winter Conferences are a place of exchange between researchers from different countries and origins, in a friendly mountaineer atmosphere. They intend to facilitate exchanges between young researchers and experts in the fields of free radicals. Organizers strongly invite participants to present free communications orally or by posters.
